Let x is the price of the book
And y is the price of the notebook,
Then,
y = x- 0.20x = 0.80x
x = (1/0.80)y
x = 1.25y

Step-by-step explanation:
We should express this word problem in an equation form:
square root of the quantity x plus 4 minus 3 equals 1 for the variable
√x + 4 - 3 = 1
The equation is:
√x + 4 -3 = 1
√x + 1 = 1
Now add (-1) to both sides;
√x + 1 + (-1) = 1 + (-1)
√x = 0
Square both sides
(√x)² = 0²
x = 0
